A student mixes 5.00 mL of 2.00 x 10-3 M Fe(NO3)3 with 5.00 mL 2.00 x 10-3 M KSCN. She finds that in the equilibrium mixture the concentration of FeSCN+2 is 1.40 x 10-4 M. a. What is the initial concentration in solution of the Fe+3 and SCN-?

b. What is the equilibrium constant for the reaction?

c. What happened to the K+ and the NO3- ions in this solution?

How does concentration affect reaction rate

What happens when an atom of sulfur combines with two atoms of chlorine to produce sci2? a. each chlorine atom shares a pair of electrons with the sulfur atom. b. an electron is transferred from each chlorine atom to the sulfur atom. c. an electron is transferred from the sulfur atom to each chlorine atom. d. each chlorine atom shares all its valence electrons with the sulfur atom.
